I use Turpenoid Natural and find it totally non-offensive. It's non-toxic, and non-flammable so I can wash my rags in the washing machine.
For medium I use only Turpenoid Natural and linseed oil, and that's only on the underpainting. Works so far. The underpainting will dry in 5 days or less, depending on the pigment and the weather.
